The counts need the entire library downloaded to compute six numbers — 16.0 MB
from Radarr and 5.5 MB from Sonarr, measured — and they were on the same
one-minute clock as queue depth and health, which pulled ~30 GB a day out of the
arrs to re-count records that had not changed. They now cache for fifteen
minutes against how often the numbers actually move: 7.6s to 3.0s per refresh.
Emby and Jellyfin get a card each: version, CPU, memory, uptime, streams, users
and transcodes, with update/restart flags. Two halves of one question — a server
answering happily at 145% CPU is a different situation from one at 8%, and
neither the app nor the container says so alone.
